SPECIFILGATIGN forming part of Letters Patent No. 699,453, dated May 6, 1902- Applioationfiled June 13, 1901 Serial No. 64,417. (No model.)

following is a full, clear, and exact deserip tion.

This invention relates to a machine for E0 weighing out merchandise by its value-that is to say, when properly set to weigh out the worth in merchandise, of a certain sum of money and to automatically cut offvthe merchandise when the proper amount has been his particularly adapted for use in connection'with retailing sugar; but of course it is applicable to various other materials, as will be obvious.

This specification is a specific description no of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to theaccompanying drawings, forming a partof this specification,

in which similar characters of reference indica'te corresponding parts in all the views.

Figure 1 is a front elevation of the invention. Fig. 2 is an enlarged front elevation illustrating the mechanism of the machine.

Fig. 3 is a top plan view of the cut-off devices 36 and the mechanism for operating them. Figs.

4; and'5 are fragmentary front elevations of the devices for operating the cut-offs, such views showing the said devices in different positions. Fig. 6 is a bottom plan view of Figs. 7 and 8 are bottom plan views of the cut-offs, said views showing the cut-oifs in different positions. Fig. 9 is a reduced sectional view illustrating the manner of hanging the sup:

port for the receptacle into which the mer-' chandise is delivered, and Fig. 10 is a sectional elevation showing particularly the triplevers which coaet with the scale-beam.

10 indicates a suitable framing for the apparatus, and 11 a hopper containing the merchandise. (See Fig. 1.) This hopper is mounted over'the frame'and has a dischargeorifice 12 in the bottom. (See Figs. 7 and 8.) The scale-beam comprises two parallel parts 14 and 15, the former being the value-beam and the latter the price-beam. These parts 14 and 15 of the beam are connected rigidly together, and the beam is fulcrumed suitably on the frame at the point 16. As shown in Fig. 2, the section 14 of the scale-beam is provided with graduations and figures representing money. The specific arrangement illustrated provides for figures from five cents up to one dollar, and on this portion of the beam '14 a weightor pea 17 is arranged. The beam 15 is provided with two graduated parts, (designated 15 and 15", respectively.) On the part 15 is arranged a balance pea or Weight 18, and'on the part 15 is arranged a sort of yoke or block 19, which is connected with the platform or support for the material to be delivered. The graduations 15 represent the price of the merchandise per pound and the graduations 15 are provided simply for enabling the balance-pea 18 to be adjusted in accordance with the position of the yoke or block 19.

The yoke 19 has a hanger 20 connected thereto, and to this hanger is connected a rod 21, which (see Fig. 9) passes down to and is connected with a lever 22, fulcrumed in the framing 10 and extending to the rear thereof. Connected with the rear end of the lever 22 is an upwardly-extending rod 23, which is joined to the rear arm 24 of a rock-shaft 25, mounted transversely in the frame. (See Figs. 2 and 9.) This rock-shaft 25 has two forwardly-projecting arms 26, from which depend rods 27, sustaining a platform or support 28. By means of this arrangementthe platform is supported directly from the rockshaft 25, but indirectly from the section 15 of the scale-beam. When the yoke or block 19 is adjusted according to the price per pound of the merchandiseto be weighed or delivered, the equilibrium of the beam Will of course be disturbed, and this equilibrium is restored by correspondingly adjusting the pea 18.

29 indicates a funnel, (see Fig. 1,) this funnel being held under the orifice 12 in the bottom of the hopper 11 and being arranged to direct the merchandise into the bag or other receptacle on the platform-28. The funnel 29 is held by a bracket 30, which is supported from a carrier 31, mounted to slide on guides 2, carried in the frame. This carrier 31 has a cord or other flexible connection 33 attached thereto, which cord passes up over a sheave 34 at the top of the frame 10 and thence downward to the rear thereof, the rear end carrying a weight 35, which balances the carrier 31 and bracket 30, so as to hold the bracket in any position desired and permitting the ad justment of the funnel 29 to suit the height of the receptacle placed on the platform 28.

As best shown in Figs. 2, 4, 5, and 10, there are mounted on the framing 10 two levers 36 and 37, theselevers extending transversely of the beam and under the same. The upward movement of the lever 36 islimited by a stopscrew 38, held in a bracket 39, and the upward movement of the lever 37 is limited by a bracket 49. The movement of the lever 30 is furtherguided by a hingedly-mounted arm 41, which is fastened adjacent to the free end thereof and extends transversely thereto, it being pivoted at its far end, as shown in Fig. 2. Connected with the levers 36 and 37 and tending to raise the same are springs 42 and 43. These springs are adjustably attached to a pivotally-mounted arm 44, mounted on the upper extremity of the frame 10. The free end of the arm 44 is provided with a device 45 for adjusting this arm across a scale 40, (see Fig. 2,) such scale bearing graduations corresponding with the graduations on the parts 15 and 15 of the beam-scale 15. The device 45 may consist of any desired means for adjusting the arm 44; but it is preferably a threaded rod connected to the arm 44 and having a nut bearing against a part stationary on the frame of the machine, as illustrated. Fig. 2 shows the beam-scale in its inactive position, in which position it is raised clear above the lever 36, and it is raised so as barely to contact with the lever 37, the springs 42 and 43 being so adjusted that the lever 37 swings higher than the lever When the scale-beam drops to the position indicated by dotted lines in Figs. 4 and 5, both of the levers so and 37 are moved downward, and when the scale-beam returns the lever 36 is first released.

Suitably mounted in the frame 10 atpoints immediately below the levers 86 and 37 are two rock-shafts 47 and 48. The rock-shaft 47 is related to the lever 36 and the rock-shaft 4-8 to the lever 37. To this end the rock-shaft 47 is provided with an arm 49, whichis capable of movement with the rock-shaft from the position shown in Fig. 4 to thatshown in Fig. 5, in which said arm 49 engages with a slight shoulder on a trigger-plate 50. This triggerplate is suitably pivoted on the framing of the machine, (at its left-hand end, referring to Figs. 4 and 5.) Aspring 51,fastened to the frame near the pivot of the plate 50, presses the same downward, and a rod 52, connected with the lever 36, normally holds the triggerplate raised above the position shown in Figs. 4 and 5.

58 indicates a device which may be of any suitable characterfor example,a bent plate, as illustrated-Which works with the free end of the trigger-plate 50 to limit its swinging movement. When the lever 36 is raised, as in Fig. 2, the trigger-plate 50 is moved upward correspondingly against the tendency of its spring 51, and should the shaft 47 then rock the arm 49 will clear the triggenplatc 50; but when the trigger-plate is lowered, as in Figs. 4 and 5, the arm 49 in rocking with the shaft 47 will engage with and be held by the trigger-plate, as shown in Fig. 5.

54 indicates a spring, (see Figs. 4 and 6,) which is coiled around in any suitable manner with the rock-shaft 47 and engaged with a part stationary on the frame of the machine and with an arm on the rock-shaft to hold it normally in the position shown in Fig. 4.

55 indicates a U shaped bar mounted loosely on the shaft 47 and held yieldingly against a pin 56 on said shaft by means of a spring 57. This spring (see Fig. (5) is coiled around the rock-shaft 47 and is fastened thereto at one end and to the bar 55 at the other end. The spring 57 presses the bar to the right (see Figs. 4 and 5) against the pin 56, so that as the bar 55 moves rightward it carries the shaft 47 with it; but leftward movement of the bar may be effected without influencing the rock-shaft 47. Mounted to slide in the frame 10 longitudinally of the scale-beam and transverse to the shafts 47 and 48 is a rod 55, which is provided with a deteut 59, adapted to strike an extension (50 of the bar 55 and throw the bar, with the shaft 47, rightward from the position shown in Fig. 4 to that shown in Fig. 5.

61 indicates a latch fulcrumed at the point '2, which is intermediate its ends. The engaging point of this latch is at the left-hand end (see Figs. 4 and 5) and is arranged to lock with a shoulder 63 on the rod 58, holding said rod in the position shown in Fig. 5. The right-hand end of the latch (ll is pressed down by a spring 64, so that when the parts are in the position shown in Fig. 4 said end of the latch (El engages an arm (55 on the rock-shaft 47. This arm holds the latch so that it is clear of the shoulder (33 on the rod 58; but when the shaft 47 is rocked, as in Fig. 5, the arm (55 passes out of engagement with the latch 01, and the spring 454 thereupon throws up the active or left-hand end of the latch 01, so that the shoulder (33 may engage therewith. Therefore as the rod 58 moves in the direction of the arrow in Fig. 4 it strikes the extension 60 of the bar 55 and throws the rock-shaft 47 into the position shown in Fig. 5, which also permits the active end of the latch 61 to move upward, so that the shoulder 63 may engage therewith, and by these devices the rod 58 is held in the position shown in Fig. 5. As shown in Fig. 2,

a retractile spring (36 is connected with the rod 58 to move it leftward, and a handle 07is connected with the rod 58 to facilitate movingit rightward. \Vhen the scale-beam moves upward, it releases the lever 35 from the position shown in Fig. 5, thus lifting the trigger-plate 50 and releasing the rock-shaft 47.

IIO

The spring 54 thereupon asserts itself and throws the rock-shaft back into the position shown in Fig. 4. The arm of the rockshaft 47 then strikes the right-hand end of the latch 61 and throws downward its point, whereupon the rod 58 is released, and the spring 66 throws it back to the position shown in Fig. 4. The lever 37 is connected by a rod 68 with a trigger-plate 69, similar to the trigger-plate 50, and pressed downward by a spring 70. When the lever 37 is moved downward, the trigger-plate 69 follows it; but the upward movement of the lever carries with it the trigger-plate. The rock-shaft 48 carries an arm 71, which is similar in function to the arm 49 in that it is arranged to engage with a shoulder on the trigger-plate 69, as indicated by the dotted lines in Fig. 5. The rock-shaft 48 is provided with a spring 72, which holds the rock-shaft normally in the position shown in Fig. 4. This spring may be arranged in any suitable manner. As here shown, it is connected with an arm 73 on the rock-shaft 48, the further function of which arm will be hereinafter brought out.

74 indicates a transverse pin or projection on the rod 58, such pin being arranged to strike against an arm 75 on the shaft 48, so that as the rod 58 moves into the position shown in Fig. 5 the pin 74 strikes the arm 75 and throws the rock-shaft 48 into the position also shown in said View. When the lever 37 is thrown down by the scale-beam, the trigger-plate 69 is moved into active position, and when the lever 37 moves upward upon the return of the scale-beam the trigger-plate 69 follows it, and thereupon the rock-shaft 48 is released, the spring 72 then acting on the rock-shaft to throw it back into the position shown in Fig. 4. As shown best in Figs. 2, 4, and 5, a rock bar or shaft 76 is mounted in the framing parallel with and adjacent to the plane of the rod 58. This rock-shaft is provided with a bent arm 77, (see Figs. 4 and 5,) which arm is in the path of the arm 73 on the rock-shaft 48 as said arm 73 moves downward into the position shown in Fig. 4. Therefore as the trigger-plate 69 releases the rock-shaft 48 said shaft turns back to the position shown in Fig. 4, and the arm 73 then strikes the arm 77 and imparts to the rock-bar 76 a partial turn. The purpose of this rock-bar will appear hereinafter. The operation just described is also indicated in Fig. 3.

As before mentioned, the hopper 11 has a discharge-orifice 12, which is indicated in Figs. 7 and8. This orifice is commanded by a valve-plate 78, which is formed with a major orifice 78 and a minor orifice 78 The valve-plate 78 is connected with the rod 58 and it moves therewith. The valve-plate 78 is movable to place its major orifice in registry with the orifice 12 or its minor orifice in registry with the orifice 12. The valve-plate 78 is held snugly in position by means of guidewheels 79 running on the under side thereof and carried on a transverse shaft 80, suitably mounted in the framing of the machine. Fig. 7 shows the valve-plate 78 with its orifice 78 in registry with the discharge-opening 12, and Fig. 8 shows the valve-plate 78 with its orifice 7 8 in registry with the opening 12. The orifices 12 and 78 are indicated by dotted lines in Fig. 7.

81 indicates a supplementary valve-plate, which is movable on rods or other suitable guides 82 in a line transverse to the line of movement of the plate 78, so that when the plate 78 is in the position shown in Fig. 7 the supplementary valve-plate 81 may cover the opening 78 and thus completely close the dischargeopening 12. This plate 81 is also movable out of the position shown in Fig. 7 to one side of the same, so as to uncover the opening 7 8 83 indicates a spring, which engages the valve-plate 81 and presses the same normally into the position shown in Figs. 3 and 7.

84 indicates a shoulder formed on a rod or.

other member 85, which is in fast connection with the valve-plate 81. This shoulder 84 is adapted to be engaged by a bent arm 86 on the rock-bar 76. A spring 87 presses down on the arm 86 to hold it normally engaged with the shoulder 84. WVhen the valve-plate 81 is moved back into the position shown in Fig. 8, the arm 86 engages by the action of the spring 87 with the shoulder 84, and the valveplate 81 is held in this inactive position against the tendency of the spring 83. When the rock-shaft 48 moves down into the position shown in Fig. 4 and the arm 73 strikes the arm 77, the bar 76 is rocked and the arm 86 is thrown upward out of engagement with the shoulder 84, and the spring 83 thereupon throws the valve 81 into the position shown in Fig. 7.

88 and 89 represent the arms of a bell-crank lever, (see Figs. 3, 7, and 8,) and of these arms the former is pressed by a spring 90 and also is turned laterally at its end to be engaged by a flange 91 on the valve-plate 7 8, as shown in Fig. 8. The arm 89 of the bell-crank lever is connected by a link 92 with a cross member 93 on the valve-plate 81. As the rod 58 is moved into the position shown in Fig. 5 by a person manipulating the hand-lever 67 the valve-plate 78 is carried from the position shown in Fig. 7 to that shown in Fig. 8. During this action the flange 91 of the valve-plate I 78 engages the arm 88 of the before-mentioned bell-crank, and the bell-crank is then moved, thus moving the supplemental valve-plate 81 from the position shown in Fig. 7 to that shown in Fig. 8 and causing the shoulder 84 to engage with the arm 86 of the bar 76, thus holding the valve-plate 81 in open position. The valve-plate 78 will be held in the same position, owing to the engagement of the shoulder 63 of the rod 58 with the latch 61.

When the two valve-plates are moved into the position shown in Fig. 8, the merchandise from the hopper 11 runs through the orifice 12 and its weight is borne on the scale-platform. \Vhen the scale-beam rises under this weight, the lever 36 is first permitted to rise. This releases the rock-shaft 4:7 and causes the latch 61 to be disengaged from the rod 58. The spring 66 then returns the rod 58 and the valve-plate 78 to the position shown in Fig. 7; but the valve-plate 81 retains the position shown in Fig. 8. Therefore the major orifice 78 of the valve-plate 78 is moved out of registry with the discharge-opening 12, and the minor orifice 78 is moved into registry with the opening. The merchandise continues, therefore, to run out through the minor opening 78, and therefore additional weight of the merchandise is placed on the scale-platform. Under the action of this additional weight the scale-beam will rise farther and in time will permit the lever 37 to rise sufficiently to release the rock-shaft 48. The rockshaft 48 in returning to the position shown in Fig. 4i operates the bar 76, and the supplemental valve-plate 81 is thereupon released. This valve-plate then returns to the position shown in Fig. 7, and the flow of merchandise is entirely cut 011. The various parts of the scale are adjusted so that when nearly all of the desired weight of the material has passed the orifice 78 of the valve 78 the valve will be operated to cut off the major supply and permit a small quantity to continue to pass by way of the minor orifice 7S", and, further, the adjustments of the mechanism are such that when exactly the proper weight has been run out the return of the scale-beam to equilibrium will be complete, and therefore the lever 37 is permitted to move sufficiently to release the rock-shaft, which release results in the closing of the supplementary valve 81.

In using the invention, assuming that the merchant be dealing in sugar and that this sugar is for sale at five cents per pound, the yoke or block 19 should be adjusted at 5 on the scale 15 (See Fig. 2.) Then in order to balance the scale beam the pea 18 should be moved to the figure 5 on the scale 15, as also shown in the View referred to Fig. 2. Next the arm as should be adjusted by the devices 45 so that it points to the number 5 on the scale 4-6. This will so adjust the levers 36 and 37 that they will work in time with the other parts of the apparatus. "When these adjustments have been made, they should be retained as long as sugar (as suming that sugar is being dealt with) retails at five cents per pound. If a change in price occurs, the parts mentioned above will have to be readjusted according to the new price. Should a customer desire forty cents worth of sugar, it is simply necessary to adjust the pea 18 to 40 on the scale 14: of the scale beam. This will cause the scale-beam to drop from the position shown in Fig. 2 to that shown by dotted lines in Figs. 4c and 5. A bag or other receptacle is placed on the platform 28, and the funnel 29 is adjusted so as properly to direct the flow of sugar into the bag. Then the hand-lever (i7 is thrown to the right, opening the valve-plates 78 and 81. The sugar now flows out of the opening 12, and guided by deflector-plates it passes through the funnel 29 into the bag. lVhen the proper weight of sugar is nearly reached, the scale-beam begins to move upward, and the first movement of the scale-beam results in moving the minor orifice 7S into the position shown in Fig. 7, whereupon a diminished flow of sugar follows, and when the exactly proper amount is delivered the upward movement of the scalebeam will be completed, and then the supplemental valve-plate 81 will move into the position shown in Fig. 7, thus completely cutting off the supply.

lVith this apparatus the merchandise may be accurately weighed, and all the operations are automatically performed except the setting of the pea 17 and the primary movement of the lever 67. In instances where a very small amount of sugar or other merchandise is to be sold it may perhaps be advantageous simply to manually set the rock-shaft 4.8 and also manually throw open the supplementary valve 81, and then when the proper value of merchandise has been delivered into the receptacle on the scale-platform the movement of the lever 37 will automatically close this valve. If desired, a hand-lever (not shown) may be provided for facilitating the manual movement of the valve 81.

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to such variations as may lie within the scope of my claims.
